6tag is being updated. Developer Rudy Huyn has unveiled the new release on Twitter, noting that 184.108.40.206 includes a number of fixes, as well as smoother scrolling. If you've encountered an issue or two, this release should hopefully improve the user experience.
6tag 220.127.116.11! Fix issue with directs (new user ids are longer than before, same issue than InstaBeta, but fixed^^) and a smoother scrolling— Rudy Huyn (@RudyHuyn) August 31, 2015
If you're rocking Instagram Beta, you may want to switch to 6tag. Intrigued to find out more? Be sure to download and install the app if you haven't already got 6tag. We expect the update to roll out to your smartphone shortly, though we're not seeing it on our end as-of-yet.
